국제물품매매계약에 관한 UN협약상 이행기전 계약위반의 성립요건

Section 1 of Chapter V of the United Nations Convention on Contracts for the International Sale of Goods (hereinafter called as "CISG") includes three articles for the anticipatory breach of the contracts. Under the first two articles, an aggrieved party may suspend its obligations (article 71) or avoid the contract (article 72) before the time for performance is due if the conditions required by the articles are satisfied. Where the parties have entered into a contract by which the goods are to be delivered in instalments, an aggrieved party may avoid the contract with respect to a single instalment, future instalments, or the contract as a whole (article 73). Anticipatory breach regulated under the CISG, which has its origin in the common law, may be supplemented by the principles of the common law, if there is any vagueness or uncertainty in the interpretation and application of the provisions of the CISG. For example, retraction of the anticipatory breach is not mentioned in the CISG, but it may be allowed until the aggrieved party has either sued for the breach, or changed his position materially in reliance on the breach, or stated that he regards the breach as final.
